 At what point in handling is a 7" wide rim better than a 5.5", For a street driven car, will I miss that wider contact patch? |

'73 with rebuilt 1.7 that is assumed to be more or less stock, even if it is warmed over a tad bit it is still not a powerhouse of a power plant (IMG:style_emoticons/default/smile.gif)
I have a choice of rims for final build.... 16x7 using one inch spacers (that more or less makes the wheel combo set heavier) (currently has 205's) or 15x5.5, no spacer. (currently has 195's) Both sets need brand new tires and since not a race car and it might see one auto-x a year no need for super sticky tires. So lets say both would get same brand middle of the road tire. I'm thinking the smaller setup would be better right off the bat due to be a lighter combo however would the lateral grip be better with the wider setup? Being a street car and being the responsible person I am, I'd venture to say that I wouldn't ever reach the point of needing the extra lateral grip if that is a something that the one combo would excel at.

Narrow tires, less footprint, will give you more of a chance to tune that 1.7 to attain 40 mpg.....or really damn close to it, with tall tires.
But, for me, I would go with the 7 inch 16s Look at Ricks car, he has those wheels, just a nice look. |
